Just thought I would let you know that you've inspired me to build an aircraft very similar to this. 80" wing span sure is a step up from what Im used to though! haha.
A really nice bit of work Ed... lots of new little ideas and tweaks to the basic EA style. I really like the poly bolts and wing-nuts... I may try them with "blind-nuts" too.
I tell you, landing gear is a huge challenge! It adds a lot of weight and complexity and I only do it on larger planes and/or planes I cannot hand launch. The best luck I've had so far is with heavy piano wire or pre-molded fiberglass, plastic, or CF landing gear struts. One-piece are better, two-piece work OK. I screw these to a piece of CF plate (from eBay) or you could use rigid plastic. This is Scotch 2-sided foam taped to the bottom and strapped on with Duck-brand duct tape.
Another great innovation Ed! This one looks like it's going to be a huge success very straight forward yet build to do the job. Can't wait to see more on this. (got to love your innovative ideas for transport) yet another aircraft we'll have to look into using in the future for BGC-Aviation.
I will do a more detailed video on the Ozone coming soon. It is more complicated than the Peace Drone, but it does have larger payload and landing gear if that is what you want. It is 2m wingspan, 1m long, 2400g. The chord of the wing, horizontal stabilizer, and horizontal stabilizer is 23cm and all control surfaces are 5cm. The wing sections are 75cm - 50cm - 75cm (left, center, right).
The trick with foamboard seems to be distributing the loads as widely as possible with the size of the landing mounting plate and the way it is attached. The foam tape seems to do a pretty good job adhering a larger area to distribute the forces on the landing gear vs. the plane. Piano wire struts have to be bent by you. The do have some 'give' on landing. Try sandwiching the wire between thin plates. Also see therevjvegas for a landing gear idea.
The drilled BBQ skewers are a great idea! You have invented for scratchbuilding what they call "K-wires" in Orthopedic surgery for the same purpose in fracture fixation. The humidity here is very low so things tend to stay together except when landing on the (irrigated) wet grass or if left in the sun. The hatch is 3 thicknesses of foamboard. Mostly just coincidence, because I overbuilt the upper panel of the pod in order to accept the wing mounts and motor mounts.
Nice I'm using some of your designs and I thank you very much for such straight forward and honest vidseo's Keep it up cause we all like to watch and learn. Thanks from NC
I love that motor and use it a lot. The 12x4 is borderline over-propped. I'd probably do the 11x4 for continual use. 45a ESC is good. Overall that setup would get you up to 1500g before it started to get underpowered. I'd rather keep it under 1200g, but if you're landing-gear-launching it can be a little heavier than if hand launching.
I really like this design, I'm looking into aircraft designs for a specific mission that will require about 30-40 minutes of flight time, and this may be the ticket. What has your longest flight been with this model or your other designs? Keep up the fantastic work ED.
Ed you should make retractable gear for that plane that retracts forwards but has a stopper for going down and back so it is strong while landing. It would make your plane faster and look cooler.
It's actually 0 degrees like most of my planes. I once worried a lot about this as I know it can be an important part of airframe design. But it seems like we can get away with having coplanar wing and stab most of the time, maybe just trim in a little bit of up elevator. To be honest I think this plane works fine as-is. To have the elevator in the prop wash makes it pretty responsive in pitch, both trim and for maneuvering.
I had three batteries in for this flight. The outer spars are a little skinnier arrows this time and there is indeed a little flex. I imagine this might take a little movement out of the center section during "turbulence" during flight and may make the camera view more steady. I'm not really certain of the physics of that, but it's a good rationalization ;) I hope to put up to about 500g worth of video camera on there, maybe a couple of GoPro's.
Sorry, I misunderstood. My Ozone has three wing sections: 30"+20"+30". For you, the center flap seems like a cool idea, but challenging with the motor mount. Maybe the fat-tapered flaps you said originally would be good. Man I wish I had a farm to fly around!
Yes, I will do a more detailed look at it on the bench. No step-by-step build video though. If you're building something of this scale then you probably already know what you're doing.
Ha-ha, no doubt, me too, if I kept them in the house. I have a 24' travel trailer (a toy hauler actually) that is all mine, and it is packed with RC stuff to be sure. Only one contest entry so far, but I think most guys are waiting as not to get one-upped if they enter too early.
The screws idea you used is a good one but must be completely tight coz once a foam-penetrating part starts to move it keeps moving, and making a larger hole. If you do this, try the tape in between the plate and fuselage to lock it in place. BTW, the Ozone uses a pretty unconventional landing gear. It was actually not hard at all, but best suited for large planes with broad side-surfaces for mounting. A detail video will follow soon.
There's a lot that could be more aerodynamic about this plane, including the booms. I built this one from off-the-shelf parts so it's pretty boxy. It definitely needs nose caps. The tail is left square so I can rest it on its rear while setting it up. The "efficiency" I speak of is just the long wingspan, low wing loading, and low Kv motor. The airframe is not that smooth at all. Maybe you'll build something like it?
lol here in florida water is in abundance. yah i might go with an amphibious cargo with wing floats, ill try for twin engine design using your techniques it will be a few weaks before i start. i have to get the electronics lined up first and do some water proofing:) cant wait to see what you have in store for us laymen.
That one I got on eBay but HobbyKing does have a very large choice of Master Airscrew props. Search the HK website for "Master Airscrew" and look at page 5 for several 3-bladed choices.
I would like to build 10 designs for EA for guys to choose from before calling it a full complement of planes, and an amphibious plane is definitely in the plans. The problem is that there are very few lakes or standing water in Arizona to fly off of. I'm thinking of something like an Axon with a step on the main fuselage plus sponsons or wing floats might work. You might want to take it on too?
Nice. How big of warehouse do you have to store all of these planes??? My wife would kill me.... How many large wingspan - 20' have entered into your contest?
Did you use an angle of incidence on the main wing (relative to the rear hor. stabilizer)? If not, in retrospect, could the plane have benifitted from using an angle on incidence?
Hi, I have built most of your planes and are very happy with them but ont thing I have had a problem with is attaching the landing gear. I put a piece of perspex on both sides of the foam board and a bolt and nut going through both as it looks like you did and all was good on concrete but when I used it on the grass the bolt started to rip a slot in the foam board from the little bumps when taking off or landing. PLEASE HELP as I want to use landing gear.
The dust was a bitch! It didn't seem to affect much from a practical standpoint except the lens. The 2.4 video link seemed very clean to me. 4000' elevation was not too bad, maybe 20% shorter flight time, but I was doing a fair amount of maneuvering too. I learned a lot about flying out there, and packing for the trip. I'd probably opt for a big-ass flying wing, and just take a second one as a spare, instead of taking 3 different planes as I did.
Hi been making my wings out of wall mart foam board not great for getting the paper of but makes up for it with being heaver paper and foam and no need to peel the paper just score and run a round dowel down the line. glue up on the paper holding up great so far wings much more stiff chuck
Oh bummer. Guess I've just gotten lucky around here. I had my own, a couple of friends, and a random acquaintance who is a pool guy. Keep an eye out though!
where do you purchase the10x6 3 bladed prop? I try to find on Hobbyking, but i can't find it, PS: i want to have the same set-up as your on my MX2 3D air plane scratch build that weight around 700g, it would be great according to your description of 1600g of static thrust, :) Thank you ExperimentalAirlines!!!
How do you calculate motor thrust? And would a Turnigy D2836/8 1100KV Brushless Outrunner Motor be capable of flying the ozone? Or is there another motor under $13 that would do the job for hking?
Very nice build! I love the yellow inner tail, makes it so much easier to identify it's orientation from a long distance.
Just thought I would let you know that you've inspired me to build an aircraft very similar to this. 80" wing span sure is a step up from what Im used to though! haha.
I still think this is the best plane youve designed. So many good design tricks in one plane.
A really nice bit of work Ed... lots of new little ideas and tweaks to the basic EA style. I really like the poly bolts and wing-nuts... I may try them with "blind-nuts" too.

Wow Ed your brain just keeps kicking out the good ones . Bravo sir and thanks for sharing .can't wait to see trip video
Your landings are SOOOOOOOO smooth.
It does look the the Shadow UAS. Great new design ideas Ed. Can't wait for some other guys to take this and further tweak it!

Very nice design. I like the foldable rudder :)
It is a 3" nominal tube, so the score interval for the internal paper facing is 3". The actual dimension is more like 3 1/2" inside.
Nice I'm using some of your designs and I thank you very much for such straight forward and honest vidseo's Keep it up cause we all like to watch and learn. Thanks from NC
Absolutely, nylon wing BOLTS with blind nuts would be the best!

Very stable. Neatly done.thanks for the vid.
Nice work on this one. I really like it

yet another piece of inspiration, i can see what im building next thanks ED
hey do you have any future plans for an amphibious design?
Brilliant design!

Thanks for the heads-up, I will check it out for the next camera purchase. They'll probably all be HD resolution for $15 by next year ;)

$3500! That would feed 50 foamie scratchbuilders for a year!

Thanks bro, the DragonLink video is coming up soon.
A 60a RCTimer ESC and it pulled about 55a with a 10x6 3 bladed prop.
That one I got on eBay but HobbyKing does have a very large choice of Master Airscrew props. Search the HK website for "Master Airscrew" and look at page 5 for several 3-bladed choices.
Is it a real RC plane. The flying looking like a RC simulator, very cool!
Great video, thumbs up. Cheers from Sint Maarten
Know where I can get any more of those 10x7's? Props like that are HARD to come by these days...
Are we going to see an "Ozone: The Building Details" video ?
This is so cool!

To be honest if you're doing FPV I wouldn't bother with flaps, but if you want to I would just make 15" ailerons outboard and 15" flaps inboard.
Mine is 22" long, but that is negotiable depending on your needs.
Have you thought about trying to make those booms have an airfoil shape?
Nice. How big of warehouse do you have to store all of these planes??? My wife would kill me.... How many large wingspan - 20' have entered into your contest?

Oh yeah, duh, forgot that. It's 2400g, so 5.9lbs AUW with 3 x 2200mAh packs and FPV setup.
very nice

what is the length from the main wing to the tail wing and what is the tail measurements
Is a build video coming any time soon?
what is the AUW, i have a similar sized FB plane but in a different configuration and it weighs around 6 pounds
Oh bummer. Guess I've just gotten lucky around here. I had my own, a couple of friends, and a random acquaintance who is a pool guy. Keep an eye out though!
where do you purchase the10x6 3 bladed prop? I try to find on Hobbyking, but i can't find it,

Hello: Great model with an excellent fly, but, where can I find the measures to be able to mount it. Greetings aerodino45
How did you bend that carbon fiber plate for the FPV backpack ?
Felicitaciones, excelente modelo, es posible obtener los planos y lista de materiales.Gracias
could you make plans?
How do you calculate motor thrust? And would a Turnigy D2836/8 1100KV Brushless Outrunner Motor be capable of flying the ozone? Or is there another motor under $13 that would do the job for hking?
Try a prop with less pitch, it will improve the flightime
you may be right, but every one i know that fly FPV use them. have a good one.
Would a 8x6 pusher 3 blade be good enough? Or a 3 blade 9x7?
What esc and how many amp in this build?
Hola: Gran modelo con una excelente mosca, pero, ¿dónde puedo encontrar las medidas para poder montarlo. saludos aerodino45
